.- :To-i all-whom iii-may. concern 1i. Be it. knownathat I,"-W'ILLIA1v1S. Enmo'rr, of Pittsburgh, Allegheny county, Pennsylwania=, have.'invented a new and useful I1n .iprovement 1n Fastening'Dev-ices forDoors, @overs,: &c., of which the following 18 a which i J Figure 1 is aiplan view illustrating my invention; Fig. 2 is a vertical section; and-Fig. 3 is a iPlELH' VIQW SllOWlng a modification.

My invention has relation to .fastenings for doors, covers, etc., beingapplicable gen-: erally foreuse in securing any removable member inplace. The object of my invention is to provide a device of thischaracter-which is simple in its construction andwhichcan-be easily andcheaply manufactured and applied.

Referring to the drawings, the. numeral 2 designates a portion of a dooror. cover plate, and 3 a portion of the memberagainst.

which the door or cover plate seats.

4: designates a double-ended bolt having an enlarged central portion 5,one of the threaded ends of the bolt being screwed into the member 3,and the opposite end portion of the bolt projecting upwardly through anopening 6 in the cover or door member, within which opening the enlargedportion 5 loosely seats.

7 designates a slotted washer, which is adapted to engage the upperthreaded portion of the bolt and to seat across the upper end of theopening 6 and between such upper end and the under side of the nut 8.This slotted washer is preferably attached to the cover or plate member,so that it will not become lost or displaced. In the construction shownthis is effected by means of the chain 9, which is attached at itsopposite end to a ring 9*. 10 designates the usual gasket in the seatingface of the nut 2. a

It will be readily seen that with the parts in the position shown inFigs. 1 and 2, the door or cover member will be securely held in itsclosed position; but that it can be readily removed by loosening the nut8, which acts as a lock for the washer, and then. withdrawing the washerfrom engagement with the bolt. To again fasten the door or cover member,all that is necessary is to reinsert the-slotted washer and tighten thenut. Preferably, the upper part of the .zenlargedaportio-n 5 of the boltis tapered orbeveled as indicated, so as to act as a guide forthe dooror the cover: int bring- :sing it to its-seat against the member 3.

ll-hediameter of the opening 6 is preferably suflicientlyl' larger thanthe maximum diiameter' of the. enlarged portion 5 so as togive.suificientclearance to prevent binding orsticking. The washer 7 ismade suffioiently larger in diameter than the diameter ofa'athe opening6 so as to give it a secure a seat. upon the edges of the opening.

.Inathemodificat-ion shown in Fig. 3, there are a plurality of thefastening devices above wdescribed-yand instead of providing a sepaz-rate slotted washer 7 for each of the bolts 4, I provide a continuousstrap 11 having a series of slots 12, there being one-slot for each ofthe bolts. This construction is especially applicable to large sizeddoors or cover plates where a plurality of fasteningsis employed; and byforming the washers asone continuous strap, all the fasten ing devicescan be simultaneously released or secured.

The device forms a very simple and effective one for the purposedescribed. It can be readily applied; there are no loose parts to becomemisplaced or lost; and the simple withdrawal or application of theslotted washer member effects the release or securing of the device.

What I claim is 1. A fastening device for doors, covers, eto.,comprising a bolt projecting rigidly from one of the members to beconnected, and having a clamping member at its outer end, the othermember to be connected having an opening therein sufliciently large tobe passed over the, bolt and its clamping member, means for centeringthe bolt with respect to the said opening, and a locking mem r arrangedto engage the bolt adjacent to its clamping member; substantially asdescribed.

2. A fastening device for doors, covers, etc., comprising a double endedbolt having an enlarged central portion, a part of which is tapered orbeveled to form a guide member, and a slotted member adapted to engageone end portion of the bolt; substantially as described.

3. In a fastening device for doors, covers, and the like, thecombination with the part to be fastened, of a bolt projecting rigidlyfrom one of said parts and having a clamping member at its outer end,the other part having an opening of suflicient diameter to pass over thebolt and its clamping member, a slotted locking device arranged toengage the bolt adjacent to the clamping member, and means for causingthe bolt to be substantially concentric within the said opening when theparts are fastened; substantially as described.

4. In a fastening device of the character described, the combinationwith a seating member having a double ended bolt secured therein, of aremovable member having an opening adapted to fit over a portion of thebolt, and a slotted locking member adapted to seat across the saidopening and to engage the bolt, together with a nut on the bolt to actas a clamp for the locking member; substantially as described.

In a fastening device, the combination with a seating member, a doubleended bolt secured in said member and projectin therefrom, said bolthaving an enlarge central portion, a removable member having an openingadapted to inclose the enlarged portion of the bolt, a slotted lockingmember arranged to engage the outer end portion of the bolt, andclamping means for Copies of this patent may be obtained for five centseach, by addressing the Commissioner of Patents.

the locking member; substantially as described,

6. In a fastening device of the character described, a seating member, abolt secured therein and having an enlarged central portion, a removablemember having an opening within which said enlarged central portion isadapted to seat, a locking member arranged to engage the outer portionof the bolt, and means for securing and releasing the locking member;substantially as described.

7 In a fastening device of the character described, the combination ofthe seating member having a plurality of bolts secured thereto andhaving projecting portions formed with enlargements, and a removablemember having openings adapted to fit over the projecting portions andenlargements of the bolts, a slotted locking member common to the seriesof bolts and adapted to seat over the said openings, and clamping nutson the bolts; substantially as described.

In testimony whereof, I have hereunto set my hand.
